Specification forming part of Letters Patent-N0. Z493. dated July 9, 1850.

To all whom it may concern: .i

neit known that I, the undersigned, GEORGE LEONARD, Jr., ot' Shrewsbnry,.in the county,

ot' Worcesterand Commonwealth ot' iviassa'chu setts, have invented 'new and useful Improvements in Fire-Arms Enibrace'd in a Pistol, of' 'which the following is a fnll and exact description, reference being had to the accompanying ldrafvings, forming part ot' this specification. It has seven barrels, (marked Bin Figures 1 and 6,) a front view ot' which is exhibited in Fig. 2 and a hack view in Fig 3. The barrels vhaven. form somewhat similar to those in a common revolving pistol. rlhey are drilled and boxed entirely through. This is never done inv revolvingpistols. '.lhey'have a breech-pin which closes the whole .seven barrels, and which fits an interior screw and cavity in the barrels exactly` The breeclipin is marked B P in Figs. 1 and Fig. 4 represents the front view, and o o o Fig. 5 represents the back view, and c c c c c c c the concs. It seems almost impossible to close all ofthe seven barrels with one breech-pin, as is here done, so as to prevent all chance of communication from one barrel to another; but it has proved practicable and easy. One-halt' of the breec'cpin projects out ofthe barrels, as shown in Fig. 1. i'lhc front part of the stock has an interior screw, which is screwed onto the projecting part ofthe breech-pin, as represented in Fig. 6, and thus connects the stock with the barrels..

The hammer H, Figs. 6, 7, and 8, revolves ou a. piu (markedjp t' oz, Figs. 6 and 7,) and strikes in regular succession, as the pistol is operated, the caps er1-the six exterior cones. Theap on the seventh or middle cone is exploded at any time by turning downl with the Enger the central hammer, C H, Figs. 6,7,-

and 8. This turning or revolutiouot the centrai hammer takes piace on a pin (marked p t' n, Figs. 6, 7, and 8,) passing .through a teilen, t, Fig. '8, to which the central hammer is tted by a mortise, and which is a portion`- of the hammer H, Figs: 6, 7, and 8. '.Ilhe central hammer when turned down )ro'ects some-A what beyond the hammer, `so as to render it iin- ,p'cssibleto explode a cap on an exterior cone l,when tiring one on the middle ccne. l'.lhe hammer has a cavity, c, Fig. 7, forcnehead of the sweep s, Fig. 6, and the head is confined loosely in the cavity by the screw s, Fig. 7.

rllhe revolving carriage R C, Figs. 6, 9, and 10, is placed in the interior of the stock, about threefonrths of' an inch back ofthe cones and' breech -pinf4 It turns on a bearing (marked b e a r, Fig. 6,) which exactly lits the interior ot' the stock, and also in a groove, G, Fig. 6,

which fits on a collar within the stock and cap of the stock c o l, Figs. 6 and 17, so as to retain the revolving carriage in its position and only allow itto turn. The hammerisattached to the revolving carriage hya pin,'(inarkedpin, Fig. 6,) and turns with the revolving carriage.

`The revolving carriage is turned by means of a ratchet, 1t, Figs. 0 and 10, which is operated upon by the ratchet-lever R L, Fig. 6, and caused to revolve one-sixth at every stroke of the hammer.

The ratchet-lever is attached to the stock by a screw, s', and to'thc cooking-lever C L, Fig. 6, by another screw, s, turned upward. lt has two slots, as shown, beneath s and s", for

these screws to pass through, and to allow longitudinal motion to enable it to slip over and fit the notches in the ratchet. Vlt is operated by the cooking-lever by means cf the screw s". The ratchet-lever is kept firmly againstthe ratchet in all positions by the ratchet-lever spring 1t L S, Fig.,6, which'is attached to the vstock by the screw sm', and bears against the back end ofthe ratchet-lever.

The mainspring M.- S, Figs. 6 and 14, is attached to the stock by thescrew 8. cavity is drilled into the other extremity or head, about one-fourth of an inch, into which one head ot' the sweep s, Fig.6,is insertedand coiltined loosely by the key k, Fig. 14, which is a. crooked wire passing down each side of the neck ofthe sweep through holes iu the head of the mainspring. The mainspring has. a.'

slot,s, Fig. 14, through which thelatch L, Figs. 6 and` 1 3, and stirrup, Figs. ti and 12, pass.

Thesweep is a cylindrical piece with two globular heads loosely confined, as ahuoye described, in the back ot the hammerI and head of the mainsprinff. The blow is communicated fJom the mainspring to the hammer 'by means of the sweep. Y The4 cooking-lever C L, Figs. 6 and 11, lies near the center of the stock. One end enters a slot in the stock. It is fastened to the 'stockbythepin b, Fig. 6. Itpasses through an aperture on the under side of the stock and terminates in a circular ring for the iin ger to pullby. It has a large slot, A, Fig. 11,for the sweep to pass through, and a groove in the upper part of the lower portion, in which the trigger T, Figs. 6 and 1l, lies and exactly fits. A shoulder on the under side.,- s h, brings up against the stock and hinders the cooking-lever from being drawn farther back than is necessary.

Y The trigger T, Figs. 6 and 11, lies in and tits the groove in the' cooking-lever, as above stated. It plays on apivot, e, and has a slot, s, Fig. 11, in its upper extremity, ilrwhich is fastened by the pivot g, Fig. 11,`a.nd plays, the stirrup s t, Figs. 6 and 12. It has a. pad to protect and sustain the tin ger marked p a d, Figs. 6 and 11.

' The stirrup s t is fastened, as above stated,

to the trigger, and has a slot` s, Fig. 12, near its lower end, through which passes the top of the cam U, Fig. 6.

The latch L, Figs. 6 and 13, enters into a continuation ot the groove already mentioned in speaking ofthe cooking-lever. It is fastened there, so as to play within, by the pin d, Figs. 6 and 13. It has as lot, s, Fig. 13, in the back end, in which. is fastened by the pinf, Fig. 6, and plays, the cam G. It passes through the slot in the mainspring, and latches onto it by the notch N, Fig. 6.

The cam Chas the position above stated. The front part of it rests on the bottom of the slot in the niainspring.

The triggerspring T S, Figs. 6 and v15, is

. fastened to thestock by the same screw, '.s",

that attaches. the.,mainsprin g to the stock. The upper end has a slot, s, Fig. 15. This slot fits over the e'nd of the latch and calm, Fig. 6, s othat the spring presses against -the pinf, which is sufficiently long for this purpose.

@A sliding band, a side view of which is seen nOFig. 16, covers the cavity occupied by the hammer and protects the hand from fragments of exploding caps.A

The pistol is operated as follows: i e' cocking-lever is pulled back by the mid le linger,

consequence the hammer.

the notch in the latch drives the mainspring back, which carries back the sweep, and of The screw s'l', Fig. 6, raises the ratchet-lever, which carries the revolving cargiage and hammer one sixth round. Mean while the tri gger-springis raised kand the ratchet-'lever spring keepsthe ratchetlever irml y against the ratchet, and the end of the trigger rises and' projects forward somewhat out of the groove in the cooking-lever. To discharge the pistol, while the middle linger still presses back the cooking-lever pull back the trigger by the forenger. This draws forward the stirrup, which pulls over the Vcamso that the front part of the cam. presses on the lower end ofthe slotinthe mainspring,liftsup the latch, and allows the mainspring to drive forward the sweep and hammer. The middle finger is now slackened, when the triggerspring drives forward the latch and cookinglever, and forces down the latch so that the notch in it will again lock onto the mainspring. When thecocking-lever is moving forward the screw s carries down the ratchet-lever, and the ratchet-lever spring then forces it forward into the next notchct' the ratchet,

What claim as my invention, and desire to secure byhetters Patent, is as follows:

1,. Acentral hammer tobe shifted from some convenient position so as to bear on the central cone and to be driven by the usual opera-y tions of the lock.

2. A revolving carriage to carry and thru the hammer.

3. A trigger turning on a pivot in the cockand which is thrown forward intoa ing-lever, position convenient to be drawn by pulling said cooking-lever. The whole to`be substantially as herein described.'

In testimony whereof I, the said GEORGE LEONARD, Jr., hereto subscribe my name, in the presence of the witnesses whose names are hereto subscribed, on the 12th day of March,

GEORGE LEONARD, JR.

In presence of- ELIZABETH DAVIS, SYLVEsTER DAVrs.
